MACHINE vFOR CHARGING COKE-OVENS.

Application filed April 25. 1907. Serial No. 370,315.

To all whom it may concern,

Be it known that I, ALFRED ERNST; a citizen of the United States, residentof Pittsburg, in the county of Allegheny and State of Pennsylvania, have made a certain new and useful Invention in Machines for Charging Coke-Ovens; and I declare the following to be. full, clear, and exact descri tion of the same, such as will enable others s illed in the artto which it a pertains to make and use the invention, refiirence being had to the ac and to letters or es of reference marked thereon, which form a part of this specification.

Figure 1 1S alongitudinal vertical section of the invention,'with the parts of the ma chine in their initial position with relation to the oven. Fig. 2 is a similar view on a larger scale, with parts broken away, and showing the charging'box within the oven, and Bthe 7 1g. 3 is a similar view showing the charging box withdrawn from the oven, leaving the false bottom and the coal charge thereupon within the oven. Fig. 4 is a similar View, showin the head plate withdrawn from the coa charge and the oven and the adjacent oven door closed. Fig. 5 is a vertical transverse section of the charging box, showing the 30' anti-friction rollers thereunder. Fig. 6 is a detail fragmentary view of the bottom portion of the head plate and the false bottom upon which it rests. Fig. 7 is a detail fragmentary lan view of the false bottom, showing t e slot therein. I

The invention relates to means for charging coke ovens witl. loose coal through the end openings or doors of the same. At present "the ovens are charged with coal through holes in the to thereof by coal lorries provided with cfiutes and having movement on top of the ovens. In such cases, the top of the coal charge is naturally of an irregular sl1a e, more coal accumulating directly below t e charging holes than in Therefore the top of the charge must be finally leveled by means of a reciprocating bar introduced into the oven through an opening in the door. Both of these operations rec uire considerable time and labor, and cause loss of gas and coal.

The obje t of the invention is the provision of an efficient andv practical combination of devices which will accomplish the desired result in the manner stated in a minimum amount of time. Other objects and advantages will hereinafter appear.'

The invention consists in the novel construction and combinations of parts, as hereinafter set forth.

y In the accom anying drawings illustrating the invention, the letter a, designates one of an alined series or battery of coke ovens, and b, a carriage or car designed to be moved along the front of the battery to be successively brought into alined position with relation to the end openings or doors thereof, a suitable trackway 0, being provided for this pur ose. The, car I), is provided with a series 0 anti-friction rollers d, upon which rests a longitudinally movable charging box 7 6, adapted to travel upon such rollers and provided with a false bottom having independent lon itudinal movement with relation to the c arging box. This box is 0 en at the top and ends, the sides being brace at the top by means of as shown.

In the operation of the invention, the charging box filled with loose coal, which filling 'is accomplished usually by means of overhead hoppers, is carried into the coke oven throu h the open door at the end thereof until it occupies the position in which f the coal is designed to rest. To accomplish this result and to withdraw the charging box and false bottom leaving the coal in its proper position in the oven, the following mechanism is provided. Sprocket wheels 9, are arranged at each end of the car I), a chain 9 connecting such sprocket wheels, and the bottom of the charging box having connection at the rear end portion thereof with said chain at 9 At the rear end portion of the false bottom f 'is provided an oblique or inclined head plate h, which forms a closure for the rear end of the charging box durin the charging operation and is provided wit lateral bracing flanges'h, connecting the samewith bottom flange 71 thereof, said bottom flange having a downward projecting lug 'L, working in a slot 2', of the false bottom. fulcrumed at its lower end to the tom, such lever having a connecting rod with the head plate h, andbeing provided with a reci rocatory awl rod is, operated by lever han le k, and adapted to engage a notch Z, at one end ofv the quadrant Z, whereby the head plate is secured against movement in its position at the rear end of false bottransverse angle bars 8,-

A lever 7', is

the charging box. This box having been moved into the oven means of the sprocket gear aforesaid-having a suitable motor con- .nection- -(not shown) a locking pin m is passed through a perforation m at the forward end of the false bottom f, which pro ing box from the oven, the false bottom of" box remaining in the oven owing to the locking pin. aforesaid. The charge of-coal also remains in position in the oven resting u on the'false bottom, the inclined head pate it, shutting a .a-inst the rear end of the coal charge. As t pleting the last portion of its movement of withdrawal, a transverse hracin angle bar e, at the forward end portion t ereof contacts with the pawl lever is, as shown in Fig. 3 of the drawings, releasing the loclring engagement of the pawl rod of such lever with the quadrant and carrying the lever back to position at the rear end of the qua rant, as shown in Fig. 4 of the drawings. At the "same time the head plate h is moved backward from the coal charge by the lever connection to a position in rear of the oven, which enables the door of the oven, to be dropped into position in rear of the coal charge upon the false bottom f. Owing to the. slight forward inclination of the head plate h, amountin to about twenty degrees to the vertical, t e rear end of the coal charge against which the head plate normally abuts and which has a similar inclination will be rendered stable and prevented from disintegration or toppling over underneath the oven door, which would prevent entire closure thereof. The false bottom f upon which rests the charge of coal is now Withdrawn from the oven by means of a rope n, having Windlass connection 0, at the rear end of the car, the locking in m, being first withdrawn from its seat, 1; e door at the forward end of the oven dropping down behind the false bottom as it is withdrawn to entirely close this .end of the oven. The coal charge is 'at the same time stripped. from the false bottom, and remains in its proper osition within the oven. The char-gin of the oven is thus 'complete it remaining on y to suitably secure'the doors at the ends of the ovens by the usual devices. for this purpose. As the false bottom of the car completes the last ortion of its movement of withdrawal, the ever 7' strikes projection p at the rear end of the car, and is moved to position at the forward end of. the quadrant (see Fig. 1 of the drawings), the head plate 7L moving for warclly therewith to position normally clos ing therea'r' end of the chargingtbox.
